In the "grayed out" portion of learning, there is a water wheel. Wonder what this could mean. Does it have something to do with the first screen shot and we saw what appeared to be a dried up river bed running to the tree? Hmm, got my curiosity going.

And I think maybe the pick 5 is your starting villagers. When you compare the ones pictured to the ones in the water at what is clearly the start of the game, at least 2 of the 3 are the same as the pick 5 shown.
